It's usually not, you're right. Reddit sports forums -- especially team specific ones -- are dominated by sports radio type garbage takes.

But you also have at least some people on reddit who are trying to go deeper, or who have more perspective, than your drunk uncle yelling at the TV. So it's a lot of shit but a decent amount of good, where sports radio is almost all shit.

If you want to know about or hear discussion around the game or something but are around other people without headphones, quietly reading what Redditors have to say is considered more polite than putting on the sports radio for everyone else to hear.
